Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Is the following statement true or false? Since momentum is the quantity of motion, all vehicles moving at the same speed will have the same momentum.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -FALSE-A less massive object would have a greater momentum owing to a velocity which is greater than that of the more massive object. Momentum depends upon two quantities * mass and velocity. Both are equally important.

Detailed explanation-2: -ANSWER: FALSE-An object has momentum if it is moving. Having mass gives an object inertia. When that inertia is in motion, the object has momentum. If an object does not have momentum, then it definitely does not have mechanical energy either.

Detailed explanation-3: -Momentum is the measurement of motion. Any moving object will have momentum. According to physics, the object’s momentum equals mass times velocity.

Detailed explanation-4: -1 Answer. Correct option (c) Momentum is conserved in all collisions but not kinetic energy.

Detailed explanation-5: -An object which is moving at a constant speed has momentum. An object can be traveling eastward and slowing down; its momentum is westward. Momentum is a conserved quantity; the momentum of an object is never changed.
